A novel PVC board and method of manufacture. The board includes a compressible layer to provide flooring that is comfortable to walk on, and a polyurethane surface that is easy to clean. The method of manufacture simplifies the production process, and improves production time and efficiency.

The present disclosure provides a touch display device including a display panel, a touch panel, and a cover plate. The side of the touch panel adjacent to the display panel is provided with a recess and a surrounding portion surrounding the recess. By vacuuming the gap formed between the display panel and the touch panel, a portion of the touch panel is recessed into the gap, which reduces the space occupied by the gap, eliminates the sense of space, enhances waterproof and dustproof effects and elevates stability.

A method is provided for manufacturing a panel that includes a substrate and a top layer provided on the substrate. The top layer may include a decor film and a transparent film. The decor film may be a printed synthetic material film chosen from the group consisting of a vinyl-based film, a polyethylene based film, a polyurethane based film, and a polypropylene film. A print may be situated on an upper side of the printed synthetic material film. The transparent film may be a thermoplastic synthetic material film the material of which is chosen from the group consisting of polyvinyl chloride, polyethylene, polyurethane, and polypropylene. The method may involve providing the decor film and the transparent film on the substrate by performing a first press treatment at an increased temperature to form a package of the substrate, the decor film, and the transparent film. The first press treatment may be performed by a calendar device or a continuous press device. A structure may be formed in the thermoplastic synthetic material that forms a surface of the package by performing a second press treatment using a press device with a structured press element at a temperature that is lower than the increased temperature.

A device for bonding a window includes a chamber having an internal space, a display panel fixing unit in the chamber and including a first curved surface, the first curved surface being configured to attach to a flexible display panel, a window fixing unit in the chamber and including a second curved surface, at least part of the window fixing unit including an ultraviolet transmitting material, the second curved surface facing the first curved surface and being complementary with the first curved surface, and the second curved surface being configured to attach to a window, and an ultraviolet irradiating unit on the window fixing unit, the ultraviolet irradiating unit being configured to irradiate ultraviolet light through the window fixing unit toward the first curved surface of the display panel fixing unit.

There is provided a display device including a first member, a window on the first member, a first adhesive layer between the first member and the window, and a light blocking layer between the window and the first adhesive layer, the window including a first window portion contacting the first adhesive layer and including a bending portion and a non-bending portion, and a second window portion connected to the bending portion, the second window portion being spaced from the non-bending portion and contacting the light blocking layer, wherein the first adhesive layer includes, a first adhesive portion including a first sub-adhesive portion contacting the bending portion, and a second sub-adhesive portion contacting the non-bending portion, and a second adhesive portion contacting the light blocking layer, and wherein the first sub-adhesive portion has a modulus less than a modulus of each of the second sub-adhesive portion and the second adhesive portion.

An inkjet printing method for manufacturing decorative laminate panels ordered by a customer includes i) providing an inkjet printing device with a print job including one or more decorative patterns and an identification code assigned to the one or more decorative patterns; and ii) printing the one or more decorative patterns with one or more inkjet inks and applying the identification code on a substrate web, wherein the substrate web is a paper substrate and the one or more inkjet inks are aqueous pigmented inkjet inks are printed on the substrate web before impregnation with a thermosetting resin; or the one or more inkjet inks are UV curable inkjet inks and the substrate web is a thermoplastic substrate web based on a material selected from the group consisting of polyvinylchloride (PVC), polypropylene (PP), polyethylene (PE), polyethylene-terephthalate (PET) and thermoplastic polyurethane (TPU).

A bare optical fiber manufacturing method includes applying an ultraviolet curable resin applied around an optical fiber; and irradiating the ultraviolet curable resin with ultraviolet light emitted from semiconductor ultraviolet light emitting elements, by use of an ultraviolet irradiation device having plural ultraviolet irradiation units each having plural positions where the ultraviolet light is emitted toward the ultraviolet curable resin, the plural positions being arranged on the same circle, the plural ultraviolet irradiation units being arranged in a traveling direction of the optical fiber such that the optical fiber passes centers of the circles, at least two of the plural ultraviolet irradiation units being differently arranged with respect to circumferential direction angles thereof around an axis that is the traveling direction of the optical fiber.

A glass composite includes a first glass member and a second glass member. The first glass member and the second glass member are at least partially connected with each other at the surfaces, and a contact interface is formed on the contacting position of the first glass member and the second glass member. The contact interface is visually observed to have no crevices; and when the glass composite is in contact with an acid solution, crevices are suitably formed in the glass composite at the contact interface.

The present disclosure provides a stretchable film and a fabricating method thereof, and a display device including the same. The stretchable film is composed of at least two layers, where each layer includes a first portion and a plurality of second portions. The first portion is a grid-like structure having a plurality of openings, and the second portion is an island-like structure in the opening. Any one of the plurality of second portions in any one layer does not completely overlap with any one of the plurality of second portions in other layers. The first portions of adjacent layers are partially overlapped, and the overlapped portions are adhered together. The first portion has an elasticity modulus that is less than an elasticity modulus of the second portion.

A method of producing a cell culture chip, in which a first adhesive is film-formed on a first substrate having transparency such that a first adhesive layer and a recessed portion on which one or more cell culture flow paths are formed face each other, and a second adhesive is film-formed on the first substrate such that a second adhesive layer and a flat portion around the recessed portion face each other, thereby obtaining a cell culture flow path substrate, the first adhesive containing a polyester-based resin having a glass transition temperature of 5° C. or higher, and the second adhesive containing a polyester-based resin having a glass transition temperature of lower than 5° C.
